摘要：

The low-temperature reactions of [Sb(NMe2)(3)] with [CyPH2] and [CyPHNa] (1:1:1 equiv,) and of [As(NMe2)(3)] with [(BuPHLi)-Bu-t] (1:3 equiv,) in TMEDA-thf [TMEDA = Me2NCH2)(2)] produce [{cyclo-(CyP)(4)Sb}Na . Me2NH . T-MEDA](2) 1 and [{cyclo-((BuP)-Bu-t)(3)As}Li . TMEDA . thf] 2, respectively; at higher temperatures these reactions generate Zintl compounds containing Sb-7(3-) and As-7(3-) anions.
